The A.H. Systems EHA-51B Antenna is an active, general-purpose, receive-only antenna that covers 1 KHz - 60 MHz.
As a monopole antenna it is ideal for instantaneous bandwidth scanning (without tuning) of electric fields in its frequency range and can drive any receiver with 50-ohm input impedance.
The EHA-51B is also an active receive only loop antenna for magnetic field testing. It is suitable for MIL-STD, VDE, and TEMPEST testing, with reliable, repeatable measurements.
